A new sweet potato variety, Won-Mi, was developed at the Crops Experiment Station, Rural Development Administration in 1986. This variety was selected from the cross between Hongmi (female) and Kogae No. 14 (male). Won-Mi showed strong resistant response to the soft rot disease during storage when inoculated artificially to sweet potato with the mycelia or spores of Rhizopus stolonifer but moderate response to black rot disease by Ceratocystis fimbriata. Yield potential of Won-Mi was 41.7 Mt/ha in marketable roots with 14 % increase and 7.00 Mt/ha in starch yield with 16 % increase compare1261d with one of the leading variety. This starch content was a little higher than check variety. The total fresh yield (vine and total root) was 87.3 Mt/ha with 10 % increase. This variety showed the better yield when cutting was carried out as the full season cropping sy
